or ieiating to Means for lnihrieating Va lvcs. otl whirli the Following is a speeifieation, rcierence being had therein to the ar winpanving drawing.

This invention relates to inil'noved means ter lubricating the. valves otf internal rouibustifn engines and refers partitularlv to f "l v rot,

The invention may he broadly described sting in providing means uhereb)v the lubricant is thrown from the interior of the crank raw through passages or. eondu-its against the said valves. the said ythrmving beingeltceird either or both 'o v centrifugal action and by a pump. 4

In the accompanying drawings. Figures 1. 2 and f3 show one method et carrying out in v invention, Fig. 1 being aV vertieal cross soetion on the line A B of Fig. Q which illustrates a four-cylinder engine the valve ot' which is shown in elevation, the drawings being a seetion on the line (l-D of Fig. 1. Fig. 3 is a horizontal section through the axis of the Valve and on the line (1l-H ot Fig. 1. Fig. tis a modification, partly in section. of the device, showi'l a passage formed in the crank, the ari. or web. of which are provided with extensions. Fig. 5 shows the web of the crank to he sloped so as to throw the oil onto the connecting rod bearings. Fig. 6 shows oups fixed to thel web of' the crank, and furnished with oil bearing extensions.

Referring to Figs. 1, 2 and 3, the webs 1 ot the frank are furnished with disks 4 running' in the oil Q in the crank ease 3 in such a manner that their rotary movement foroi bljv th rows the oil in their -plane of rotation. A portion of this oil is` Athrown along the conduits 5 arranged beside the cylinders 8 and falls against the wall of-the valve (l.

It ivill be seen, particularly in Fig. 2, thaty the outlets 7 from the conduits 5 are placed out of the paths of the ports 9, 91", 93. il* and 10', 102, 103, 104, so as to avoid leakage. The oil on the valve carried around by it and owing to the slight free pla)Y between the valve and its easing travels thoroughly orer the bearing surface ef the valve being spread out so as to thorouglilv lubrieate it. Grooves such as 11, 11. 12, 13 and 13 are preferably provided in the valve easing and are of interrupted helical form for the purpose of preventing direct cominunieation hetween the inlet to one cylinder and the exhaust of another, during,` the rotation oiC the valve.

ln the moditication shown in Fig. L1 a passage is formed in the crank the. arms or Webs 14 of which have extensions 1:3 and the oil is forced through the passages and thrown out of the extensions, or the oil ma;v be collected by means of cups on the crank.

1n Fig. 5 the web of the crank is sloped at 1G, 16, so as to throw the oil onto the connecting` rod hearings, the oil having a tend" eney to travel to the edge 17 of the said slopes.

In Fig. ti the arrangement shown (foinprises cups 18 fixed to the web of the Crank and furnished with extensions 19 through which the oil is thrown on to the bearings.

Having now particularly described and ascertained the nature ot' my said invention and in what manner the same is to be performed, l declare that what I claim is 1. Means for lubricating valves, comprising a casing, the lower part of which oon- .stitutes an oil receptacle, a crank in said casing having a web, a disk on said web adjusted to Contact with the oil in said receptacle. conduits in the plane of rotation of said disks upon which the oil is thrown from said disks and conducted to the wall of the valve. the movement of the valve causing` the oil to be spread over its bearing surface.

2. A device for lubricating the slide valves of internal combustion engines, comprisintf a Casing forming an oil receptacle,

a crank shaft in said casing, means upon the crank shaft for projecting the oil, conuis disposed in the planes of projection, and tangential to the exterior trajectory, of the crank shaft, cylinders adjacent to the seid conduits, a slide valve at the ends of Said conduits receiving the oil projected by the crank shaft, the said conduits opening into placement of the distribution oifce In testimony whereof I ux my signtizi'efl in the presence of-tWo witnesses.
